Many of the village names in ancient Thracia were composite, with the
words -para (-phara, -pera, -parōn,
etc.) ‘a village’, -bria ‘a town’ and -diza (-disza,
-dizos) ‘a fortress’ as a second element:

Such names are not to be found in Dacia proper (on the northern side
of the Danube), in Dobrudzha and most of Northern Bulgaria except its southern
eras, where there were seven such names: Mitzipara, Longinopara, Agatapara,
Beripara, Kistidizos, Maskiobria, *Alaaibria. The Dacian linguistic
area is characterized with composite names ending in -dava (-deva,
-daua, -daba, etc.) ‘a town’. The village names in -dava,
-deva, are geographically grouped as follows:

Besides these regions, similar village names are found in three other places:

Thermi-daua (Ptol.), a town in Dalmatia. A Grecized form of *Germidava.
This settlement was probably found by immigrants from Dacia.

Gil-doba – a village in Thracia, of unknown location.

Pulpu-deva (Iord.), Old-Bulg. Pləpədibə
(XII c. AD), Plodivə
(XI c. AD), known under the Greek name of Philippopolis (Liv.,
Plin., Ptol., etc.). The town was named after the conqueror Philip
II of Macedon (359-336 BC). It is improbable, however, that ‘Pulpudeva’
was imposed to the local inhabitants by the Macedons. Village names in
-deva are not found in Macedonia except Desu-daba in north eastern Macedonia,
somewhere around the town of Kochani. This village, however, is attested
late – by Livius. Most probably, it was founded by immigrants from Dacia
mediterranea, where such names (e.g. Aiadaba, Kuimedaba) were common. The
name of Pulpudeva must be explained as a translation of the Greek
Philippopolis
by the locals, who used -deba – a borrowed word from the north, from the
Moesian tribes of the present Northern Bulgaria. The Slavic Pləpədibə,
Plodivə was derived from this Pulpudeva.

In any case names with -dava, -deva are exception in Thracia and cannot
be regarded as proper Thracian. There is a clear geographical distinction
between the place names ending in -para, -bria, and -dizos (the Thracian
ones), from other side, from those ending in -dava, -deva (the Dacian ones)
.

There is a number of other, phonetic differences between Dacian and
Thracian:
